Yes
call a locksmith
I have a 97 Cavalier,,,and one key does the door , ignition and trunk.
Lock smith! They can either open the door or make you a duplicate key (no master key needed).
Smash the window that's the best way
Assuming you lost the keys, write the vehicle identification number down on a piece of paper, take that and proof of ownership to your local Chevy dealer and they can reproduce new keys for you.
Are the keys in the ignition? If so all you have to do is take them out when you open the door.
Open the keys with the door.
There is always the trunk release button in the driver side door, toward the bottom.
Remove the rear seat, and use a really long extention to unbolt the latch from inside of the trunk.
Call a locksmith, they will come to your car. Road towing service can get in with a shim but may damage door. you can break a window if desperate. Call someone who has the extra set of keys.
== == Pull on the inside door handle and it will release it so you can reset the mechanism with your fingers. This solution also worked on a Chevy Astro van 1990.
